FREIGHT-CAR LOCK.

Application filed May 20, 1920'.

and which will not interfere with the sliding bar-k of the door whenit'is desired to open it. Experience has shown that in the past whenfreight car doors were locl red and sealed only at one side, it waspossible for thieves to wedge the back edge of the door away from theside of the car without d1sturbing the lock and thus gain access to thefreight within the car, and my invention obviates that possibility. Y Mylock may be made of steel, iron or any other suitable inaterial whichwill be strong enough to make the lock secure. i

My invention is illustrated more or less diagrammatically in theaccompanying drawings wherein Figure 1 is a side elevation of thefreight car door, in the closed position on the car;

Figure 2 is a section along the line 22 of Figure 1.;

Figure 8 is a. front elevation of the lock;

Figure 4: is a section along the line l4l of Figure 3;

Figure 5 is a section along the line 5-5 of Figure 3;

Like parts are indicated by like charactors in all the drawings.

A is a sliding freight car door having the lock plate A at the back edgethereof. The look A is fastened to the door at one end by means of abolt A which projects far enough out from the door frame to allow thelock to swing down when the car door is opened. The bolt is tightened inposition on the door frame by means of a nut A and the shoulder Aresting on the washer A allows the head end of the bolt to projectsufficiently to permit the lock to swing down when the door is opened asabove referred to. The lock is fastened at its other end to the car bodyby means of a bolt A which has an eye shaped head A The bolt eye islocated in a recess in the car wall. and the bolt is held in position bya specification of Letters Patent.

nut and washer. The look plate A is slotted as at A to engage theeyerU'and is so shaped that it has a plurality of perpendicular parts,one parallel the car door the hex perpendicular thereto, a thirdparallel with and adapted to rest against the car wall and the nextperpendicularto it and adapted to penetrate the recess, and the last,the slotted part parallel the first and adapted to pass over the bolteye.

C is the usual form of hasp fastened at one end to the car door by meansof the staple C, and slotted at the other end in the usual manner toengage the staple C The hasp is held in place on the staple by the pin9*. v

.ihe use and operation of my lnvention are follows:

The lock plate is permanently attached .to the car door by a bolt whichis allowed to project sufficiently to leave play for the lock plate toswing down perpendicularly on the door when not in use. When the door isclosed and it is desired to lock it more securely than, and in additionto the ordinary hasp and. staple lock on the forward portion of thedoor, my lock plate is swung up to a horizontal position, the slotslipped over the eye bolt, and locked in position by a quarter turn ofthe eye bolt. This bolt is sunk into a groove in the car frame just deepenough to permit the top of the bolt to come flush with the outersurface of the car frame and thus does not interfere with the opening ofthe sliding door.- The pin is then slipped through the eye of the boltand the seal is attached to the lower position of the pin. This makes itimpossible to wedge open either side of the car door without breakingthe seals on the locks.

I claim:

1. A look plate for freight car doors consisting of a unitary platecomprising a' plurality of perpendicular sections at right angles witheach other and adapted to engage the several surfaces of the freight cardoor and the car body, one part of the lock plate slotted and adapted topenetrate a recess in the car body.
